Description

Capacitive touch screen panel {ELECTROSTATIC CAPACITY TYPE TOUCH SCREEN PANEL}

The present invention relates to a fixed capacitance type touch screen panel.

In recent years, display devices such as liquid crystal displays (LCDs), electroluminescent displays, and plasma display panels have attracted attention because of their high response speed, low power consumption, and excellent color recall . Such display devices have been used in various electronic products such as televisions, computer monitors, notebook computers, mobile phones, display parts of refrigerators, personal digital assistants, and automated teller machines. Generally, these display devices constitute an interface with a user by using various input devices such as a keyboard, a mouse, and a digitizer. However, the use of a separate input device such as a keyboard and a mouse has been required to learn how to use the device and to inconvenience such as occupying a space, thereby making it difficult to improve the completeness of the product. Therefore, there is a growing demand for an input device that is convenient and simple and can reduce malfunctions. In accordance with such a request, a touch screen panel has been proposed in which a user directly contacts a screen with a hand or a pen to input information.

The touch screen panel is simple, has little malfunction, can be input without using a separate input device, and can be operated quickly and easily through the contents displayed on the screen. .

The touch screen panel includes a resistive type in which a metallic electrode is formed on a top plate or a bottom plate in accordance with a method of detecting a touched portion to determine a touched position as a voltage gradient according to a resistance in a state in which a direct current voltage is applied, (Electrostatic capacitive type) which detects the position where the voltage change of the upper and lower plates due to the touch is sensed by forming the equal potential on the conductive film and reads the LC value induced by touching the conductive film And an electro-magnetic type in which an indented portion is detected.

1 and 2, a description will be made of a conventional touch screen panel of a capacitance type according to the related art. 1 is a plan view of a capacitive touch screen panel according to the related art, and FIG. 2 is a cross-sectional view taken along line II ′ of the touch screen panel shown in FIG. 1.

1 and 2, a conventional capacitive touch screen panel includes an electrode forming portion A, a routing wiring forming portion B, and a pad portion C formed on the substrate 10, respectively. .

The electrode forming portion A may include a plurality of first electrode patterns 40 arranged side by side in a first direction (eg, X-axis direction) on the substrate 10 and first electrode patterns 40 adjacent to each other. Bridges 20 connecting the first and second electrode patterns 50 arranged side by side in a direction crossing the first electrode patterns 40 (eg, the Y-axis direction).

The routing wire forming unit B includes a plurality of first routing wires 61 electrically connected to first outermost electrode patterns 40 of the plurality of first electrode patterns 40, respectively, The second electrode patterns 50 include a plurality of second routing lines 63 electrically connected to the outermost second electrode patterns 50, respectively.

The first and second routing wires 61 and 63 made of a single metal layer, or the insulating layer 30 formed thereon are weak in hardness and are vulnerable to scratching, so that the touch screen panel is applied to the display device. Scratch may occur during the panel process or the module process to short-circuit or disconnect the first and second routing wires 61 and 63 in a region not overlapping with the first and second electrode patterns 40 and 50. As described above, in the conventional capacitive touch screen panel, when the first and second routing wires 61 and 63 are shorted or disconnected, the touch screen panel is not touch-recognized even when a touch is made.

It is composed of one electrode pattern, characterized in that adjacent pairs of the first electrode patterns are connected to each other by the first connection pattern.

In the above configuration, it is preferable that the first scratch prevention layer is formed so as to overlap at least a portion of the first and second routing wiring portions on the second insulating layer in the routing wiring forming portion.

In addition, a plurality of first pads respectively connected to the plurality of first electrode lines through the plurality of first routing lines and a plurality of second electrode lines through the plurality of second routing lines, respectively.

According to the capacitive touch screen panel of the present invention, since the scratch prevention layer is formed on the second insulating pattern of the routing line forming portion, it is possible to prevent scratches from occurring in the second insulating pattern and / or the routing lines underneath. Accordingly, the effect of preventing the wirings from disconnection or short circuit can be obtained.

In addition, since the electrode patterns formed on the outermost side of the electrode forming unit A are not connected to the scratch prevention layer, parasitic capacitance is not generated, thereby improving the touch performance of the touch screen panel.

In addition, since the scratch prevention layer formed on the insulating pattern of the routing wiring forming portion B adjacent to the pad portion C is formed at a predetermined distance from the pad portion C, the wiring for connecting the pads to the external circuit is scratched. Since it is not in contact with the barrier layer, an effect of improving the touch performance of the touch screen panel may be obtained.
